Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to an automatic condom-donning device for a vaginal ultrasound probe used for medical ultrasound examination. Background Art

[0002] Color Doppler vaginal ultrasound (also known as intracavitary B-ultrasound) is a very common gynecological examination method for adult women. It is a method of clinical ultrasound examination by inserting a vaginal ultrasound probe into the vagina or rectum. It is mainly used to observe pelvic organs in the small pelvis. Compared with traditional abdominal color ultrasound, vaginal ultrasound has the advantages of clearer and more realistic images, more accurate results, and does not require patients to hold their urine. Therefore, vaginal ultrasound is widely used in a variety of clinical diagnoses such as pregnancy examinations, uterine space-occupying diseases, and ovarian tumors.

[0003] Before undergoing a vaginal ultrasound examination, the patient usually needs to empty the bladder and assume the lithotomy position. Medical staff will wear disposable gloves, apply ultrasound coupling agent on the surface of the vaginal ultrasound probe, put on a condom, and then insert the probe into the body for examination. In this way, doctors can obtain accurate images of pelvic organs such as the uterus and ovaries at close range, which is helpful for the diagnosis of uterine and adnexal diseases. However, existing medical staff still have some shortcomings in this manual operation process, especially in terms of operational hygiene and prevention of cross infection.

[0004] To ensure the hygiene of the operation process, medical staff need to wear disposable gloves and put on disposable protective covers for ultrasound probes. In recent years, a variety of disposable ultrasound probe latex isolation covers have appeared on the market. Many hospitals' ultrasound departments have adopted these isolation covers in clinical examinations. In theory, they can effectively isolate the probe from the patient's body surface, block the spread of bacteria and viruses, and ensure the hygiene and safety of the examination process.

[0005] However, in the existing operation process, medical staff still need to put on and take off the isolation cover by hand, which poses obvious health risks. At the same time, ultrasound doctors do not change a pair of gloves for each patient. After each use, the gloves of medical staff will come into contact with the isolation cover, the body surface of the person being examined, and the probe many times, which cannot completely block the spread of bacteria and viruses, and there is a risk of cross-infection. In addition, the manual operation of putting on and taking off the cover is not only cumbersome and time-consuming, but also consumes additional resources, affecting work efficiency.

[0006] Therefore, in order to solve the above problems, there is an urgent need for a device that can automatically put on a condom to ensure the hygiene and safety of the probe during intracavitary examination, reduce the operation time and energy consumption of medical staff, avoid cross infection, and meet the infection control requirements of the hospital. Through this automatic condom-putting device, work efficiency can be improved, patient safety can be ensured, and medical operation procedures can be improved. Summary of the invention

The lower end of the telescopic rod 412 is arranged in the fixed cylinder 411. A limiting boss 415 is fixedly arranged at the lower end of the telescopic rod 412, and the upper surface of the limiting boss 415 is in contact with the top of the inner side of the fixed cylinder 411. The side wall of the limiting boss 415 is in sliding contact with the inner wall of the fixed cylinder 411, and a return spring 414 is vertically arranged between the lower surface of the limiting boss 415 and the inner bottom of the fixed cylinder 411. The upper end of the telescopic rod 412 is fixed with a front The end pressure plate 413, the upper surface shape of the front end pressure plate 413 is adapted to the front end shape of the vaginal ultrasound probe 12, so as to better fit the end film of the rolled latex isolation sleeve 8 to the front end outer surface of the vaginal ultrasound probe 12, and the front end pressure plate 413 is arranged opposite to the axis of the sleeve 11; in the specific implementation, the front end of the vaginal ultrasound probe 12 presses against the rolled latex isolation sleeve 8 and presses downward against the front end pressure plate 413, so that the front end pressure plate 413 compresses the return spring 414 through the telescopic rod 412, and then the front end pressure plate 413 elastically presses the end of the rolled latex isolation sleeve 8 under the reaction force of the return spring 414 to make it fit to the front end outer surface of the vaginal ultrasound probe 12.

[0032] The rotating assembly 42 with elastic telescopic teeth includes a fixed bracket 421, a rotating bracket 422, a rotating shaft 423, a fixed rod 424, an elastic telescopic tooth 425 and a telescopic spring 426.

The outer end of each elastic telescopic tooth 425 can rotate through the corresponding open groove 15 and thus pass through the interior of the wearing sleeve 11. The elastic telescopic tooth 425 is made of rubber or silicone material with a certain friction force. This design can increase the friction between the elastic telescopic tooth 425 and the open curling edge of the rolled latex isolation sleeve 8 and can prevent the elastic telescopic tooth 425 from causing damage to the rolled latex isolation sleeve 8; the rotating bracket 422 A rotating motor 427 is fixedly installed on the outer wall, and the output shaft of the rotating motor 427 is fixedly connected to the rotating shaft 423. A baffle 428 is fixedly provided at the end of the rotating bracket 422 away from the wearing sleeve 11, and a limiting plate 429 is fixedly provided on the fixed bracket 421 at a position above the baffle 428. The upper surface of the baffle 428 contacts the lower surface of the limiting plate 429, thereby limiting the upward movement of the baffle 428 so that the rotating bracket 422 remains in a horizontal state, that is, when the vaginal ultrasound probe 12 is inserted, the outer surface of the peripheral side of the vaginal ultrasound probe 12 will squeeze the elastic telescopic teeth 425 downward, thereby causing the elastic telescopic teeth 425 to have a tendency to rotate downward, thereby driving the end of the rotating bracket 422 There is a tendency to rotate downward, and then the baffle 428 at the other end has a tendency to rotate upward.
